This was more noticeable when the highest amount of salt (200 g L À1 ) was added, especially for those non-polar compounds showing highest molecular weights (log K ow > 6) such as PAHs with a high Table 1 Retention times (Rt), log octanol water partition coefficients (K ow ), accurate masses of selected ions in GC-APGC-ToF-MS, method detection limits (MDL), instrumental detection limits (IDL), calibration curves, and coefficients of determination (R 2 ) for target compounds.…”

We developed a simple, sensitive, and specific analytical method for prometryn using gas chromatography-mass spectrometry (GC-MS). Prometryn is a selective herbicide used for the control of annual grasses and broadleaf weeds in cotton and celery crops. On the basis of high specificity, sensitivity, and reproducibility, combined with simple analytical operation, we propose that our newly developed method is suitable for use as a Ministry of Food and Drug Safety (MFDS, Korea) official method in the routine analysis of individual pesticide residues. Further, the method is applicable in clams. The separation condition for GC-MS was optimized by using a DB-5MS capillary column (30 m×0.25 mm, 0.25 µm) with helium as the carrier gas, at a flow rate of 0.9 mL/min. We achieved high linearity over the concentration range 0.02-0.5 mg/L (correlation coefficient, r 2 >0.998). Our method is specific and sensitive, and has a quantitation limit of 0.04 mg/kg. The average recovery in clams ranged from 84.0% to 98.0%. The reproducibility of measurements expressed as the coefficient of variation (CV%) ranged from 3.0% to 7.1%. Our analytical procedure showed high accuracy and acceptable sensitivity regarding the analytical requirements for prometryn in fishery products. Finally, we successfully applied our method to the determination of residue levels in fishery products, and showed that none of the analyzed samples contained detectable amounts of residues.

“…The current trend is to develop simple, miniature, automatic, high selectivity and recovery sample pretreatment techniques in order to achieve the trace level pollutant analysis. Solid phase extraction (SPE) [2][3][4], solid phase microextraction (SPME) [5][6][7], liquid-phase microextraction (LPME) [8][9][10], stir bar sorptive extraction (SBSE) [11,12] and cloud point extraction (CPE) [13,14] are new methods which have been used for the separation and preconcentration of diverse analytes and have solved some of the problems mentioned above of conventional techniques. Nevertheless, some drawbacks still exist for these techniques.…”

Dispersive liquid-liquid microextraction (DLLME) is a novel microextraction technique with a great potential in sample pretreatment, which has been increasingly used for preconcentration of diverse analytes. This review updates the state of the art and discusses promising prospects of DLLME, especially focuses on its combined use with chromatographic techniques for organic compounds analysis in environmental water samples. General and specific concepts of the fundamental theory of DLLME are described, and examples of recent innovations and applications are provided to demonstrate its potential for the determination of a wide range of organic compounds in various water matrices. Moreover, some limitations related to DLLME are also discussed in detail, and an outlook on the future of the technique, specifically its coupling with other pretreatment approaches, separation and detection techniques, is also given.
